      Description

      When implementing a simple template and the tiles servlet is not defined in the web.xml you get a NullPointer exception at line 144 when running. This can be difficult for the implementer to realize what they did wrong. A suggestion would be to throw and exception when the context is null. It might be better to throw a TilesException however the interface defines a JspException so I used it.
